Multimodal Higher-Order Brain Networks: A Topological Signal Processing Perspective
Breno C. Bispo, Stefania Sardellitti, Juliano B. Lima +1
Brain connectomics is still largely dominated by pairwise-based models, such as graphs, which cannot represent circulatory or higher-order functional interactions. In this paper, w…

Interdependent scaling exponents in the human brain
Daniel M. Castro, Ernesto P. Raposo, Mauro Copelli +1
We apply the phenomenological renormalization group to resting-state fMRI time series of brain activity in a large population. By recursively coarse-graining the data, we compute s…
